Styling & Theming

The project uses Tailwind CSS v4 via the @tailwindcss/vite plugin. All theme customization lives in src/styles/global.css.

Color Tokens

Custom colors are defined in a @theme block and available as Tailwind utility classes (e.g., bg-bears-bg, text-bears-accent):

Token	Value	Usage
`bears-bg`	`#121212`	Page background
`bears-bg-light`	`#F5F5F5`	Light background variant
`bears-text-onLight`	`#2B2B2B`	Text on light backgrounds
`bears-text-onDark`	`#E1E1E1`	Text on dark backgrounds
`bears-accent`	`#C50E1F`	Primary accent (BEARS red)
`bears-accent-muted`	`#A00B19`	Muted accent variant
`bears-bg-surface`	`#1F1F1F`	Surface-level background
`bears-bg-elevated`	`#303030`	Elevated surface background

Custom Utilities

Scrollbar

@utility scrollbar-bears-thin {
  @apply scrollbar-thin scrollbar-thumb-gray-200/10 scrollbar-track-transparent;
}

Used on scrollable containers (docs sidebar, code blocks) for a minimal, dark scrollbar.

Plugins

@tailwindcss/typography — Prose styling (used in PostLayout and DocsLayout)
tailwind-scrollbar — Custom scrollbar styles

Animation System

All entrance animations are defined as keyframes in global.css. Each animation class is applied to its corresponding component and supports stagger delays via animation-delay.

Class	Duration	Effect	Used by
`.filter-chip`	0.25s	translateY(4px) + fade	Filter chips in FilterMenu
`.filter-group`	0.3s	translateX(-8px) + fade	Filter group headers
`.sort-option`	0.2s	translateX(-6px) + fade	Sort menu options
`.nav-link`	0.25s	translateX(-8px) + fade	Mobile nav links
`.accordion-item`	0.3s	translateY(8px) + fade	Accordion items
`.showcase-card` / `.face-card`	0.28s	translateY(8px) + scale(0.98) + fade	Post cards, face cards
`.post-container`	0.5s	translateY(12px) + fade	Post detail page
`.metadata-card`	0.4s (0.15s delay)	translateY(8px) + fade	Post metadata sidebar
`.contact-card`	0.35s	translateY(10px) + fade	Contact page cards
`.search-result`	0.15s	translateY(4px) + fade	Search dropdown results
`.sponsor-card`	0.3s	translateY(8px) + scale(0.97) + fade	Sponsor logos

All animations use ease-out timing and animation-fill-mode: both.

Stagger Pattern

Components apply incremental animation-delay to create stagger effects:

{items.map((item, i) => (
  <div class="showcase-card" style={`animation-delay: ${i * 60}ms`}>
    ...
  </div>
))}

Responsive Breakpoint Strategy

The project follows a mobile-first approach with specific breakpoint guidelines:

Breakpoint	Width	Usage
Base	< 640px	Mobile styles (default)
`sm:`	640px+	Minor adjustments (spacing, font sizes)
`lg:`	1024px+	Major layout changes (column direction, grid columns)
`xl:`	1280px+	Optional refinements for large screens

Skip md: for layout. The 768px–1024px range often creates cramped layouts on tablets. Use sm: + lg: for structural changes:

<!-- Good: skip md: for layout -->
<div class="grid grid-cols-1 lg:grid-cols-2 xl:grid-cols-3">

<!-- Avoid: md: creates awkward tablet layout -->
<div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3">

Reserve md: for fine-tuning (spacing, font sizes), not structural changes.

Headline Spacing

All h2 section headings use a consistent bottom margin:

<h2 class="mb-8 sm:mb-10 lg:mb-14">Section Title</h2>

This provides 32px → 40px → 56px across breakpoints for a coherent visual rhythm.

Focus Indicators

Global keyboard focus styles are defined in @layer base:

a:focus-visible, button:focus-visible, input:focus-visible, ... {
  outline: 2px solid var(--color-bears-accent);
  outline-offset: 2px;
}

Firefox Compatibility

Firefox has poor compositor performance with backdrop-filter. A @supports (-moz-appearance: none) block disables backdrop-filter on .showcase-badge and replaces it with a solid semi-transparent background:

@supports (-moz-appearance: none) {
  .showcase-badge {
    backdrop-filter: none !important;
    background-color: rgba(0, 0, 0, 0.75);
  }
}

Reduced Motion

When prefers-reduced-motion: reduce is active:

All entrance animations (.showcase-card, .accordion-item, .nav-link, etc.) are set to animation: none
Button transitions use near-zero duration (0.01ms)
Button transforms are disabled
Alpine.js animation code checks the media query and skips transitions

Pagefind Search Highlights

Search excerpt highlights use the BEARS accent color at 30% opacity:

.search-excerpt mark {
  background-color: color-mix(in srgb, var(--color-bears-accent) 30%, transparent);
}
